Students in Chongqing, China can use their mobile phones as cards to borrow books from libraries, purchase meals, and gain access to dorms, among other things, according to People’s Daily Online.

The multi-service platform, developed by Chongqing Telecom, is a one platform that combines the functions of a dining card, student ID, library card, access card and other necessary cards on campus and replaces it with a mobile phone.

A similar system combined the functions of bus cards and bank cards into a mobile phone. Chongqing Telecom’s new service platform expanded the services to include those to include those found in a campus environment.

The system has already been piloted in schools and will be expanded to the public early next year.
